Abstract

A system for and method of controlling the heat input in a welding operation are provided. The system includes an arc welding power supply configured to output a welding waveform (200) to a welding torch. The welding power supply includes a waveform generator to generate an output welding waveform. The power supply also includes a controller to optimize the output welding waveform (200) based on one of a desired RMS voltage set point and a desired RMS voltage range. The optimization is performed by adjusting at least one of a power ratio and a duration ratio. The power ratio is a ratio of a power of a negative portion (208) of the welding waveform (200) to a power of a positive portion (210) of the welding waveform (200), and the duration ratio is a ratio of a duration (tEN) of a negative portion (208) of the welding waveform (200) to a duration (tEP) of a positive portion (210) of the welding waveform (200).
